Conclusion

The path to CMMI level 4 contributed to the business objective by giving::

  • visibility in the future with a known level of confidence
  • improving all the processes thanks to the measurement vision
  • return on investment due the earlier defects detection, the improvement
  • f risk management and better control of our programs

We have learnt to put a process under statistical control and use this skill to extend the number of processes controlled statistically. The future leads us to improve the product obsolescence projects management, to improve the selection of process improvements and to reduce the number of defects injected.
